EJECTING-PENI-IOLDER.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed December 6, 1907. Serial No. 405,377.

To all whom tt may concern:

Be it known that I, SAMUEL KELLOGG WILL- soN, a citizen of the UnitedStates, residing at Dwight, in the county of Hampshire and State ofMassachusetts, have invented certain new and useful Improvements inEjecting-Penholders, of which the following is a specification.

This invention relates to the class of pen holders, and moreparticularly to those with means for eject-ing the pen points when it isdesired to insert a new one, and has for its object to provide a simpledevice of this character whereby the pen nib may be ejected in aneffective manner and without soiling the fingers.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in t-he specificstructure shown and described may be made within the scope `of the claimwith out departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side elevational View of the pen holder, Fig. 2 is avertical longitudinal sectional View through the same, Fig. 3 is a crosssectional view on the line 3-3 of Fig. 2, Fig. 4 is a cross sectionalview on the line 44 of Fig. 2.

Referring now more particularly to the drawings, there is shown a penholder comprising the tubular stock 11. The outer end 10 of the stockhas formed, therein, a face which gradually enlarges toward the outerextremity 14 and receives the pen nib- A and an outer enlarged end 14.Arranged in the tapered end of the stock there is shown a pen ejectingplug 15 comprising the resilient jaws 16 and 17 respectively. These jawsare arranged to conform to the tapered end of the stock, as shown. Aplunger 18 is arranged to work in the hollow portion of the stock at thebutt end thereof, and this plunger is thus arranged to receive one endof a slidable coil spring 19 which is arranged between the plunger andthe jaws 16 and 17 respectively. The outer'end of the spring is securedto the plug 18 as by means of the eye 20. The spring at its inner end isalso attached to the inner end of the jaws 16 and 17 by means of asimilar eye 21. The plug 18 is retained in the stock by any suitablemeans, as the pin 22 extending transversely through the plug and havingits extremities disposed in the slots 23 formed in the upper and lowerportions of the stock. It will thus be seen that a pen A may beinsertedbetween one of the jaws 16 and 17 and the wall of the stock 11,and by reason of the resiliency of these jaws the pen will be securelyheld to the stock. Vhen it is desired to eject the pen the plunger 18 ispushed forwardly in the stock thus contracting the spring 19, and inthis movement of the plunger 18, when the tension of the spring 19 isgreater than the frictional force holding the spring plug in position,the jaws 16 and 17 will be pushed outwardly of the forward end of thestock 11, whereupon the pen point will be expelled. After a nib has beenejected, the plunger and the pen-holding elements are manually returnedto their original position by the operator.

What is claimed is:

A penholder having a tubular stock, a coil spring slidably arrangedwithin the stock, a spring jaw ejector plug within the end of the stock,and engaging therewith to clamp a pen nib, said ejector plug being curedat its inner end to one end of the spring, and an operating plungerslidably held within `the other end of the stock and secured to theother end of the spring, whereby when the plunger is pushed into thestock the spring will be compressed against the resistance of theejector plug, and subsequently overcome said resistance and expand toforce the plug from the stock sufficiently to release the nib.

In testimony whereof I aHiX my signature,

` in presence of two witnesses.
